Scroll of Maelstrom

To my left (Hi-Jacked from WoWInsider) is a new item. People may hail it as the 'casual' friendly scroll. That's what I thought at first. But, let me break it down into a few possible scenarios:

Farm for Weeks
Okay, so... you've got Vashj on farm status. Good for you! Now, for whatever reason, you want to outfit all the casual folks in your guild (yes, there are 'casual' guilds who can do raid content). So, it takes 1 week per scroll, that's 24 weeks which is 4 weeks less than the sequel to 28 Days Later, which is exactly 6 months. So, it will take HALF A YEAR to attune a group of casuals to front their own assault upon Serpentshrine. This method is possible, but in no way is it some sort of godsend to casuals.

Selfish Bastards/N00bs in Serpentshrine
If there is some reason you guys aren't consistently downing Nightbane or Gruul or able to do a Heroic Slave Pens. Then there is DEFINITELY something wrong with how your guild operates. If it's simply unwilling to help, or just pushing forward with a small group of 25 or so folks... that would be the only reason I would see for them being unable to wtfpwn old content that's on farm status. If they're downing Vashj, there is NO reason why they shouldn't be able to help you.

Rogues? Hunters? Sorry, wait in the back of the line.
While we're assuming that there is 1 scroll per day, and that Serpentshrine can only be run once a week, and it's using the 'Farm for Weeks' scenario. You're going to have a LOT of DPS classes sitting in the back seat for classes like Tanks & Healers who are always vastly more 'key' and 'rare' compared to the over abundant DPS classes. So, you'll be at the tail end of the list, perhaps 2 or 3 months after they have Vashj on farm status.

Overview
Okay, this is DEFINITELY not a godsend for Casuals unless she drops multiple scrolls at once, she may not even have a 100% drop chance for the scroll to begin with. I think it's a nice step in the right direction, but I see it more as a 'Get your alt attuned' thing, or even a 'Let's help that Holy Priest get into our raids since he's unavailable on the days we run Karazahn.' sort of deal.
